如何在android中添加带有节头的ListView上的拖行？

我的应用程序有问题，我不知道问题出在哪里？ 当我想把两行“mAdapter.addItem”（“项目1”，“项目888”）；”只放一行时，我不能。 谁能帮帮我吗

public class MainActivity extends ListActivity  {

private CustomAdapter mAdapter;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    mAdapter = new CustomAdapter(this);
    setContentView(R.layout.activity_main);


    mAdapter.addSectionHeaderItem("Second Item on the list");
    mAdapter.addItem("Item 1","Item 888");
    mAdapter.addItem("Item 2","Item 888");
    mAdapter.addItem("Item 3","Item 888");
    mAdapter.addItem("Item 4","Item 888");
    mAdapter.addItem("Item 5","Item 888");

    mAdapter.addSectionHeaderItem("Second Item on the list1");
    mAdapter.addItem("Item 6","Item 888");
    mAdapter.addItem("Item 7","Item 888");
    mAdapter.addItem("Item 8","Item 888");
    mAdapter.addItem("Item 9","Item 888");
    mAdapter.addItem("Item 10","Item 888");

    setListAdapter(mAdapter);

}
}

您的类

CustomAdapter

没有带签名的函数

addItem（String，String）

，它有一个带签名的函数

addItem（String）

public class CustomAdapter extends BaseAdapter {

private static final int TYPE_ITEM = 0;
private static final int TYPE_SEPARATOR = 1;

private ArrayList<String> mData = new ArrayList<String>();
private TreeSet<Integer> sectionHeader = new TreeSet<Integer>();

    mInflater = (LayoutInflater) context
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
}

public void addItem(final String item1) {
    mData.add(item1);
    notifyDataSetChanged();
}

public void addSectionHeaderItem(final String item) {
    mData.add(item);
    sectionHeader.add(mData.size() - 1);
    notifyDataSetChanged();
}

@Override
public int getItemViewType(int position) {
    return sectionHeader.contains(position) ? TYPE_SEPARATOR : TYPE_ITEM;
}

@Override

    return 2;
}

@Override

}

@Override
public String getItem(int position) {
    return mData.get(position);
}

@Override
public long getItemId(int position) {
    return position;
}

@SuppressLint("InflateParams") 
public View getView(int position, View convertView, ViewGroup parent) {
    ViewHolder holder = null;
    int rowType = getItemViewType(position);

    if (convertView == null) {
        holder = new ViewHolder();
        switch (rowType) {


        case TYPE_ITEM:
            convertView = mInflater.inflate(R.layout.list_item_m, null); //snippet_item1
            holder.textView = (TextView) convertView.findViewById(R.id.list_content1); // here problem ?
            holder.textView = (TextView) convertView.findViewById(R.id.list_content2); // here problem ?
            break;


        case TYPE_SEPARATOR:
            convertView = mInflater.inflate(R.layout.header_m, null); //snippet_item2
            holder.textView = (TextView) convertView.findViewById(R.id.separator);
            break;


        }
        convertView.setTag(holder);
    } else {
        holder = (ViewHolder) convertView.getTag();
    }
    holder.textView.setText(mData.get(position));

    return convertView;
}

public static class ViewHolder {
    public TextView textView;
}

}

因此，我认为您在以下几行中遇到编译错误：

mAdapter.addItem("Item 1","Item 888");
mAdapter.addItem("Item 2","Item 888");
mAdapter.addItem("Item 3","Item 888");
...

您试图使用两个字符串参数调用

addItem（）

函数，但该函数不存在。我不知道您想要完成什么，但您可以通过将这些行更改为以下内容来编译它：

mAdapter.addItem("Item 1");
mAdapter.addItem("Item 2");
mAdapter.addItem("Item 3");
...

祝你好运。
